SPECIFICATION forming .part of Letters Patent No. 264,273, datedSeptember 12, 1882,

Application filed October 11, 1881. (No model.)

To all whom it may concern:

Be it known that I, ROBERT P. GARSED, a citizen of the United States,residing at N orristown,in the county of Montgomery, State ofPennsylvania, have invented a new and useful Improvement in PneumaticBell -Ringing Apparatus, which improvement is fully set forth in thefollowing specification and accompanying drawings, in which Figure l isa side elevation of the bell-ringing apparatus embodying my invention.Fig. 2 is a side elevation of a portion thereof, enlarged. Fig. 3 is alongitudinal section of Fig. 2. Fig. 4 is an end view of Fig. 2.

Similar letters of reference indicate corresponding parts in the severalfigures.

My invention consists of a pneumatic bellringing apparatus of simple andinexpensive construction, as will be hereinafter fully set forth.

Referring to the drawings, A represents a hollow sphere or ball ofrubber or other suitable elastic material, which is fitted to ahemispherical shell or holder, B, the latter being adapted to be securedto the frame of a door or other proper support.

0 represents a plunger of rigid material, which is connected to slidingrods or bars D, which are passed through openings in the flange or rim Bof the holder 13, said rods retaining the plunger in position andguiding it in its motions. The ends of the rods D, opposite to theplunger 0, are secured to a plate, E, which is provided with an eye, F,for attachment of the bell-pull G, whereby when the latter is operatedthe plunger is forced against the ball A.

In the ball are openings at b, the opening a being adjacent to theplunger 0, and the opening 1) communicating with a pipe, H, which issecured to the holder B and opens into the ball, said pipe being securedin position to the wall and ceiling or other proper support.

To the end of the pipe opposite to the place of connection with theholder B is secured an elastic head, J, of rubber or other suitablematerial, which is adapted to come in contact with the spring arm or rodK of a bell suitably hung.

When the parts are in their normal position the opening a of the ball issufficiently uncovered to permit the entrance of air into the ball andinflate the same.

When it is desired to ring the bell the pull G is operated as usual.This compresses the ball and forces the air therein through the pipe Hagainst the head J, which, expanding or being forced out against the armK, moves the latter, thus ringing the bell. l/Vhen the pull is let gothe ball is permitted to expand, and the plunger and pull are therebyreturned to their normal positions, the ball then being replenished withair through the opening a. The air in the pipe H returns to the ball,whereby the head J contracts or-ass umes its normal shape, and thebell-arm is again moved, thus further ringing the bell. head J may,however, be assisted by a spring suitably applied or occasioned bygravity, and in the return. motion strike a pin attached to the arm K.

It will be seen that I produce a pneumatic bell-pull which isinexpensive, simple of construction, compact, and easily applied andoperated.

If desired, a whistle may be substituted for the head J as a signal inlieu of the bell.

The head J may be formed of rubber faced with metal, in order to guardsaid head from the wearing action of the bellrod.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. The concave holder B, provided withguide-flange B and a port, in combination with pipe H, communicatingwith said port, compressible sphere A, communicating with said port andpipe, plunger 0, bearing against the other side of said sphere, arms D,connect ed to said plunger and passing through said guide-flange, and abell-pull which operates said guide, substantially as set forth.

2. The hollow sphere, inclosed in the holder, in combination with theplunger connected to rods which are guided by the holder and providedwith means of attachment to the bellpull, substantially as and for thepurpose set forth.
